खोज दृश्य में सूची दृश्य कस्टम एडाप्टर

Question

दोस्तों मुझे कुछ मदद की ज़रूरत है। मैं अपनी परियोजना में एक खोज दृश्य को लागू करने की कोशिश कर रहा हूं। लेकिन मेरे प्रोजेक्ट में एक कस्टम एडाप्टर के साथ एक सूचीदृश्य है .. मैंने कई खोजे हैं साइटों लेकिन सभी एक arrayadapter..Lets का उपयोग कर कार्यान्वित उदाहरण कहते हैं कि मैं एक कर्मचारी वर्ग है और यह उनके नाम केवल का उपयोग कर कर्मचारियों को फिल्टर करने के लिए मैं नाम और उम्र fields..How शामिल ..

public class MainActivity extends Activity implements SearchView.OnQueryTextListener 
{ 
SearchView mSearchView; 
ListView mListView; 
//String mStrings[]= {"abc","def","efg","ghi","ijk","apple","agxhsdgc","abbbcc"}; 
ArrayList<Employee> emp_list=null; 
EmployeeAdapter emp_adapter=null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mSearchView=(SearchView) findViewById(R.id.searchView1); 
     mListView=(ListView) findViewById(R.id.listView1); 

     emp_list=new ArrayList<Employee>(); 
     emp_list.add(new Employee("ABC", 24)); 
     emp_list.add(new Employee("ACB", 24)); 
     emp_list.add(new Employee("BVF", 28)); 
     emp_list.add(new Employee("BRT", 28)); 
     emp_list.add(new Employee("ANM", 23)); 

     emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list); 
     mListView.setAdapter(emp_adapter); 

//  mListView.setAdapter(new ArrayAdapter<String>(this, 
//    android.R.layout.simple_list_item_1, 
//    mStrings)); 
     mListView.setTextFilterEnabled(true); 
     setupSearchView(); 


    } 
    private void setupSearchView() 
    { 
      mSearchView.setIconifiedByDefault(false); 
      mSearchView.setOnQueryTextListener(this); 
      mSearchView.setSubmitButtonEnabled(true); 
      mSearchView.setQueryHint("Search Here"); 
     } 

     @Override 
     public boolean onQueryTextChange(String newText) 
     { 

      if (TextUtils.isEmpty(newText.toString())) { 
       mListView.clearTextFilter(); 
      } else { 
       mListView.setFilterText(newText.toString()); 
      } 
      return true; 
     } 

     @Override 
     public boolean onQueryTextSubmit(String query) 
     { 
      return false; 
     } 


    } 

और यह मेरा है एडाप्टर क्लास जो बेसएडाप्टर को बढ़ाती है ..

public class EmployeeAdapter extends BaseAdapter { 

    Context ctx; 
    ArrayList<Employee> emp_list; 
    LayoutInflater linf=null; 
    EmployeeHolder holder=null; 






    public EmployeeAdapter(Context ctx, ArrayList<Employee> emp_list) {

अच्छा जवाब है, लेकिन अभी भी वहाँ कुछ मुद्दों (गलत स्थिति जब onclick, serchview हैं टेक्स्ट ओवरले) जैसा कि टिप्पणी खंड में उल्लिखित है, ताकि आप इसे अनुसरण करके भी कर सकें अधिक जानकारी के लिए जिस तरह से ing
